Retracting or/and supporting periurethral tissue

Abstract

Urological (prostatic) implant, system, and method for retracting or / and supporting periurethral tissue enclosing a prostatic urethra along lengths of prostate lobes, for example, in BPH patients. Prostatic implant includes independently actuatable distal retractor incorporating craniolateral corners and proximal retractor incorporating caudolateral corners. Retractors may be connected via elongated spine member, and formed as paired curved wing-liked structures having interconnecting members. May further include tissue support members extending between elongated edge members connecting retractors to spine member, and tissue support members extending between elongated edge members and spine member. Tissue support members are sized and configured for supporting portions of prostatic lateral lobes when spine member engages anterior interlobar groove extending between prostatic lateral lobes, and when elongated edge members engage posterolateral interlobar grooves. System and method include implant manipulator detachably connected to implant elongated edge members, for manipulating and forcing implant caudolateral corners into close proximity, for delivery into subject.

Description

FIELD OF THE INVENTION[0001]The present invention, in some embodiments thereof, relates to the field of urological medical devices and applications thereof, and more particularly, but not exclusively, to a urological (prostatic) implant, system, and method for retracting or / and supporting periurethral tissue enclosing a prostatic urethra along a length of prostate lobes.BACKGROUND OF THE INVENTION[0002]Benign prostate hyperplasia (BPH), also known as benign prostatic hypertrophy, is a urological disease in which the prostate enlarges and constricts the urethra. BPH affects a majority of the male population over 50 years of age, and is thus of great medical and commercial importance.[0003]Surgical treatment of hypertrophy of the prostate has been a routine procedure for many years. One method of such surgical treatment is open prostatectomy wherein the gland is totally or partially removed. Another method of surgical treatment is transurethral resection of the prostate (TURP).

Benefits of technology

[0021]According to some embodiments of the invention, the left and right posterolateral interlobar grooves, by continuously exerting a radially directed pushing force thereupon, within a range of between about 100 grams and about 1,000 grams, so as to prevent or minimize axial or / and rotational movement of the anchored anterior interlobar groove, and, the left and right posterolateral interlobar grooves.

[0024]According to some embodiments of the invention, at least one of the first and second elongated edge members comprises a caudal-nose portion shaped and configured for resting against a narrowing, imposed by external urethral sphincter adjacent to verumontanum of the prostatic urethra, so as to prevent caudal migration of the implant through external sphincter and into bulbar urethra, when the spine member engages an anterior interlobar groove that extends between the prostatic lateral lobes, and when the first and second elongated edge members engage corresponding posterolateral interlobar grooves. Optionally, the caudal-nose portion is “L” shaped.

[0035]According to some embodiments of the invention, at least one of the implant first and second craniolateral corners are shaped and configured for resting against a ledge imposed by urinary bladder neck so as to prevent cranial dislodgement of the implant into urinary bladder, when the spine member engages an anterior interlobar groove that extends between prostatic lateral lobes, and when the first and second elongated edge members engage corresponding posterolateral interlobar grooves.

[0036]According to some embodiments of the invention, at least one of the implant first and second caudolateral corners are shaped and configured for resting against a narrowing imposed by external urethral sphincter adjacent verumontanum of the prostatic urethra, so as to prevent caudal shift of the implant, when the spine member engages an anterior interlobar groove that extends between prostatic lateral lobes, and when the first and second elongated edge members engage corresponding posterolateral interlobar grooves. Optionally, each of the implant first and second caudolateral corners has a shape or form of a proximally directed apex, the apex being formed by intersection of converging curved slopes of respective ones of the implant first and second caudolateral corners.

[0037]According to an aspect of some embodiments of the present invention, there is provided a method for retracting or / and supporting periurethral tissue enclosing a prostatic urethra along a length of prostate lobes, the method comprising providing an implant along a chosen length of the prostate lobes. Optionally, the method also includes exerting continuous radially directed pushing forces upon an anterior interlobar groove between the prostate lobes, and upon at least one of left and right posterolateral interlobar grooves between the prostate lobes, thereby anchoring the implant in-place. Optionally, the method also includes exerting lateral pressing forces upon one or more prostatic lateral lobes, thereby retracting or / and supporting the periurethral tissue.

[0053]leaving the implant to continuously exert radially directed pushing forces upon the anterior interlobar groove and at least one of the left and right posterolateral interlobar grooves, so as to prevent or minimize axial or / and rotational movement thereof, or / and to increase distance separating the superior interlobar grooves and to increase distance separating the left and right inferior-lateral interlobar grooves.

Problems solved by technology

Surgical treatment is an invasive procedure that may be debilitating, painful and traumatic to the patient.

Such surgical treatment may result in various complications including impotence, incontinence, bleeding, infection, and other undesirable problems.

However, such a procedure may result in pain and discomfort to the patient.
